I realise that the doses used for hex in pct are much lower than those used for suppression on sex steroids but all that means is you downregulate some gnrh receptor rather than most of them.
Honestly this notion of hexarelin being useful is pct is completely falicious and does not agree with the science behind it.
So using hex in pct just means you lower testosterone at a time when you really want to boost it.
By the way, no doubt someone will post "that" study of hex showing a test increase. It's true, hex will increase test immediately after administration. This is logical as it is a gnrh agonist so will increase test production INITIALLY. This is known as the flare effect. But then you get a big drop in test following that increase as the gnrh receptors downgrade. The study (and I have only seen 1), conveniently only shows this initial flare and not the subsequent cliff edge of test production thereafter.
